A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbors or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, and some are icebreakers or salvage tugs. Early models were powered by steam engines, which were later superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours.
HMS Warspite was one of five Queen Elizabeth-class battleships built for the Royal Navy during the early 1910s.

Other than that battle, and the inconclusive Action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. During the interwar period the ship was deployed in the Atlantic Ocean and the Mediterranean Sea, often serving as flagship, and was thoroughly modernised in the mid-1930s.
